3,7-Inter-m-phenylene-4,5,6-trinor-9B-PGD, compounds

ABSTRACT

Prostaglandin analogs with the following cyclopentane ring structure: ##STR1## are disclosed along with intermediates useful in their preparation and processes for their preparation. These analogs are useful for the same pharmacological purposes as the prostaglandins, particularly and especially as blood platelet aggregation inhibitors.

The present application is a divisional application of Ser. No. 614,242,filed Sept. 17, 1975, now issued as U.S. Pat. 4,016,184, on Apr. 5,1977.

The present invention relates to prostaglandin analogs for which theessential material constituting a disclosure therefor is incorporated byreference here from U.S. Pat. No. 4,016,184, issued Apr. 5, 1977.
